the answers in 6 cells need to be *0.387 these round up or down (this is ok)
but when i need to add these up 6 cells up its still taking the 3rd decimal
place in to account eg 15*0.387= £5.81, 10*0.387=£3.87. 30*0.387=£11.61 these
3 are duplicated once more, when i add them up the answer is coming out as
£42.57 and shoud be £42.58 plase can you help me

The value displayed is not the actual value; if the "rounding" occurs
through formatting, the unrounded value is used in computations.
Use the ROUND() function to really round, or use ToolsOptionsCalculation
and check "Precision as displayed", but read HELP to find out what happens.

I had to read between a lot of line for this one. If I take
15*.387 + 10*.387 + 30* .387, I got 21.285. This number, multiplied by 2,
is 42.57

I'm not sure where 42.58 is coming from.

Your initial formula is not rounding but just showing to 2 decimal places I
would guess, so the result of

15*.0387 is showing as 5.81 but is actually 5.805.

When you sum the results, it adds the actual values, not the displayed
values.

Either round initially

=ROUND(15*0.387,2)

or change the sum to round

=SUM(ROUND((B1:B6)*(0.387),2))

where B1:B16 are the multipliers. This is an array formula, it should be
committed with Ctrl-Shift-Enter, not just Enter.
